Image restoration: QRBF is brightfield deconvolution of PSD, Mexico #35

Open JohnTigue opened 4 years ago

"B.G.-M. and M.d.J.S.M. are inventors on a patent application that describes QRBF."

Just terminology here:

From the fluorescence crowd:

Z stacks are usually required for deconvolution of epi-fluorescence microscopy data to remove the out-of-focus signal collected within each individual image.

So, we're working with brightfield, not fluorescence but out-of-focus is out of focus.

Get the code going where the anti-PSF kernel is a parameter. It could be a theoretical function or it could have been determined experimentally.

Maybe two tools here: one uses point spread function to filter for boutons and synapses (more point like) and the second tool uses a line spread function to filter for axons and dendrites.

Test polystyrene objects should be calibrated in size to match desired resolver (ball size of synapse, wire size or axon).

Sounds a lot like Microscopy: Deconvolution Microscopy (David Agard).

JFT on twitter:

And when it comes to addressing PSFs in a brightfield microscopy setting, this seems to be the cutting edge (this is 2014; they have a 2017(?) later paper further developing this work.
